VARNISH.

SPECIFICATION forming part of Letters Patent No. 305,636, dated September 23, 1884.

Application filed July 18, 1884. Specimens i To ail whom, it may concern.-

. cation.

The object of my invention is to provide a varnish for finishing wood and like surfaces Well adapted to resist the action of water and changes in temperature. To this end I provide the following ingredients of first quality: of cowrie (kauri) gum, one and one-fourth pound; of beeswax, one-half pound; of linseed-oil, three-fourths gallon; of turpentine, (more or less, according as it is desired to have the varnish dry with greater or less rapidity.) The ingredients are placed in a suitably-heated pan or kettle and boiled and thoroughly commingled until reduced to the proper consistenoe. The compound is then run into a vat or cooler, that it may settle and clarify, after which it is thoroughly strained to remove impurities and foreign matters.

The product resulting from this operation is a varnishlight in color but heavy in body, which will dry rapidly and present a smooth, hard surface thoroughly impervious to water.

The varnish possesses the great advantage of having a heavy body and-of being susceptible of finish by pumice-stone and oil or pumicestone and water, and of being adapted to take a dead-finish.

Having thus described my invention, what 1 claim is- Y The herein-described varnish, consisting of 5 kauri gum, beeswax, turpentine, and linseedoil in proportions substantially such as herein specified.

In testimony whereot'I hereunto set my hand, this 17th day of July, 1884, in the presence of 40 two attesting witnesses.

JOHN A. SHEPHARD.
